SELF-SUPPORTING WINDOW 84835.

Application filed March 29, 1926. Serial No. 98,187.

My invention relates to a metal window sash, and more particularly to a structure which may be aiflxed to a supporting surface perpendicular to the plane of the glass, without an auxiliary supporting member having a surface parallel with the pane.

In the accompanying drawings, F gure 1 is a cross-section through a sash embodying one form of my invention, and Fig. 2 1s a view similar to Fig. 1 showing an alternalk'ge shape of one of the glass clampmgmem- In Fig. 1 there is shown a supporting member 10 which forms a part of the frame surrounding the window opening. This supporting member has a surface 11 substantially perpendicular to the plane of the glass pane 12.

The glass is held in place by an inner clamping member 13 and an outer clamping member 14. The inner clamping member has a flange 15 adapted to lie against surface 11 of supporting member 10. An upright portion 16 of clamping member 13 extends from the inner side of flange 15 in a direction generally parallel with the plane of pane 12. In the structure shown, there is an offset portion 17 adjacent the surface of supporting member 10. A flange 18 extends from the edge of portion 16 to the inner side of the glass, and a flange 19 extendsv from the edge of flange 18 towards member 10 and is adapted to lie against the inner surface of the sheet of glass.

A' bracket member 20 fits within inner member 13 between theflanges thereof. This bracket member may be like that shown and claimed in my patent on metal window sash #1,570,702, granted January 26th, 1926, or of anyother suitable construction. The essential features are that it shall fit within the inner sash member so as to stiffen the sash member, and that it shall have a passage opening towards the outer sash member. In accordance with the present invention this bracket member has an extended flange 21 extending forward from its bottom portion and lying upon flange 15. A screw 22,

' or other suitable fastening device, passes and extending from flange 23 towards supporting member 10. At the lower edge of the outer clamping member there is an inwardly. turned flange 25. Preferably, there is a head 26 along the edge ofthe outer clamping member, which rests against sur-, face 11 and is adapted to contact the outer edge of flange 15. Flange 25 extends upwardly and inwardly from bead 26. Flange 25 may lie against the upper side of flange 15, but preferably is spaced slightly away therefrom.

An L-shaped draw-plate has the end of one arm 27 resting against flange 24 and the other arm 28 extending into the passage within bracket member 20. The angle of the draw-plate is connected to flange 25 of the outer clamping plate. In the structure shown, the connection is made by a small portion 29 of flange 25 being turned upward through an opening 30 in the draw-plate. Arm 28 is provided with a surface 31 at an angle to surface 11. A screw 32 working within a bushing 33 in bracket member 20 is adapted to contact surface 31 and thereby force arm 28 inward until the outer clamping member is brought into suitable engagement with the glass, and then to retain the. draw-plate in the position to which it is thus adjusted.

The structure above described may be used at thebottom, sides or top of a pane of glass. When used at the bottom of a pane of glass, a block, not shown, will be provided for supporting the pane of glass. Similar blocks may be provided at the sides and the tops of the glass if desired.

In assembling this structure, the inner clamping member, with brackets 20 suitably positioned at spaced intervals therealong, is placed against surface 11 and attached to supporting member 10 by screws 22 through flange 21 of each bracket 20 and the subjacent flange 15 of lnner clamping member 13. Thereafter the glass sheet is placed in position within the opening and rested against flange 19. Then outer clampin member 14, with the draw-plates attache thereto at suitable intervals, is placed in position with head 26 against surface 11 and flange 24 against the outer surface of the glass. Arms 28 then enter passages in the corresponding brackets 20, and operation of screws 32 produces the desired amount of resilient pressure upon flanges 24 and 25 and maintains the draw-plate in position to continue this resilient pressure. It will be readily seen that bracket members 20 will sufiicientl stiffen and support inner clamping mem er 13 While the draw-plates will hold the outer clamping member 14 in adjusted position.

The structure shown in Fig. 2 is the same as that shown in Fig. 1, except that the configuration of the outer clamping plate is changed, and the cooperating arm of the draw-plate is correspondingly modified to fit within the outer clam ing member. The parts in Fig. 2 are desi ated by the same reference characters as t e parts in Fig. 1, with the letter a added; and as the relation of the parts and the operation thereof is the same as in Fig. 1, a detailed description of the sash shown in Fig. 2 is unnecesft will be readily understood that various changes may be made in the structure of the various parts and in their connection with each other, within the scope of the ap pended claims, which define my present invention.
